TAPE-APPLYING FASTENERfiETTING MACHINE.

Application filed November 24, 1924.

This invention relates to machines constructed to feed reinforcing tape to be fixed by fasteners such for example, as lacing studs or other barrel fasteners to work in which the fasteners are set, though it should be understood that the invention in its broader aspects is not limited to any particular type of fasteners.

According. to the present invention a -sec tion of tape of suflicient length to receive the desired number of fasteners to be set in series in a piece of Work is defined by a weakened portion in the tape before the first fastener of the series is set so that the tape may be readily. parted at this weakened portion after the last fastener of the series has been set. This weakened portion of the tape is of sufficient strength to cause the tape back thereof to be fed as the length through which the series of fasteners is to be set is fed so that after the last fastener of the series has been set the forward end of the tape back of the weakened portion is presented in proper position to be engaged by the first fastener of a succeeding series.

Preferably bias tape is employed as this may be made to conform to the contour line of the series even though it be curved. A machine functioning substantially in the manner above described has been shown and claimed broadly in the application of Harold A. Evans and George WV. Jacques, Serial No. 705,239, filed April 9, 1924. For the purpose of insuring proper presentation of the bias tape so that it may be made to closely conform to the line of fasteners without particular attention on the part of the operator, means are provided in the present invention to place the tape under tension at the proper times.

This invention also provides means by which the adjusting of the machine to regulate the spacing of the fasteners also adjusts the length of the tape sections as defined by the weakened portions-to correspond therewith.

Further this invention provides means by which the proper length of tape sections is ensured even though the total number of fasteners to be set in series is changed, togethcr with means to properly centralize the sections relative to the series.

Provision is also made by which an individual fastener may be set where, by any mischance, one or more of a series should Serial No. 751,934.

fail to be set in the normal running of the machine, or in any case where it is desired to repalr an upper by setting an individual fastener therein.

Further advantageous combinations of parts and details of construction will appear from a more complete description of an embodiment of the invention disclosed in the accompanying drawings in which Figure 1 is a side elevation of a oortion of a lacing hook setting machine showing the tape applying mechanism applied thereto.

Figure 19 is a detail of the treadle'mechanism for actuating the clutch, presser foot and tape slitting mechanisms.

Referring first to Figures 1, 6, 10, 17 and 18, 1 indicates a punch and set mechanism carrier reciprocable in the line of feed of the work and carrying a bar 2 vertically slidable therein which supports at its lower end a combined punch and set 3. This mechanism may be of any suitable form, but herein shown is a portion of the well known P661" less hook setting machine. At 4 is indicated the work plate of the machine on which the work is supported, the punch and set 3 be ing designed to punch work supported there on, the punch and set mechanism then feeding laterally into the position shown in Figures 6, 13, 17 and 18, where the hook is presented to the work and set therein by suitable reciprocation of the bar 2.

In order to present a tape to be fixed by the hooks as set to the work, a guide mechanism indicated generally at 5 is provided. As shown this mechanism is slidable lengthwise on a slideway 6 at the upper face of a support 7 fixed to the rear face of the work table 4:. This guide mechanism comprises, as shown best in Figures 1, 2, 3 and G, a block 8 having adovetail groove therein to receive the dovetail guideway 6 and which extends forwardly of the guideway 6 where it is formed with a slot 9 through which a tape 10 may pass in substantial a-linement with the line of feed of the punch 53. This slot 9 is cut in from the forward face of the block at its forward end. It is shown as bridged by a cover plate 11 which extends over the outer end of the slot and is fixed to the block by means of a screw 12, this cover plate also extending over one side face of the block as at 13 (see Figures 2 and 13) to form with the adjacent side face a guide way for a vertical reciprocating knife 1%. A screw 15 passes through this face 13 and into the block so that this cover plate is fixed in position on this side also. hrough this plate 13 is cut a slot 16 throughwhich the tape passes beneath the. knife 14.

Above the slot 9 the block 8 is cut downwardly to form four spaced posts 20., 21, 22 and 23. Between the pairs of posts 20, 22 and 21, 23 is slidable a crosshead 25 having a central portion of reduced circular cross section as at 26 (see Figure Beneath each end of this crosshead a spring 27 is positioned bearing at its lower end at the base of the slot between the corresponding posts and on its upper end on the corresponding portion of the crosshead. These springs act normally to hold the crosshead raised upwardly as far. as is perinittedby a lever 30 pivoted at 31 between the posts 22 and 23, the rear end of this lever having a laterally extended bearing portion 32 adapted to bear downwardly against a wedge shaped slide riding on the upper face of the block 8 above the guideway 6. To one end of the crosshead is fixed by a screw 35, the knife 14, and at the other end of this crosshead is fixed a slidingplate 4,0 which is adapted when the plate is in fully depressed position to impinge on the tape pass ing through the slot 9 of the block and hold it against the lower edge of this slot to prevent it from being drawn therethrough. In the downward position of these parts the knife 1 1- passes entirely through the tape to form a slot therethrough between its side edges which are left uncut. This knife furnishes a means for weakening the tape to define sections each of an uncut length suitable to be made fast to the work by a series of a desired normally plural number of hooks. The sliding of the block 8 along the slideway 6 toward and from the hook setting mechanism furnishes means by which the length of the sections may be adjusted to conform to the number of studs which it desired to set in a series and to the spacing of such studs in the work. As will later appear means is provided for automatically adjusting this mechanism to correspond with the adjustment of the machine for spacing the hooks.

After passing through this tape guiding and weakening mechanism, the tape passes to a tension mechanism before it reaches the hook setting mechanism 3. As shown this tension mechanism fixed. to the hook setting mechanism to partake of its feed and reciprocati've movements. As shown best in Figures 1, l, 5, 6 and 10, this mechanism comprises a bar 4:5 having a portion at its upper end of reduced rectangular cros section to fit within a slot 46 in a ring 1-? (see Figure 13), this ring fitting and being clamped to the car' er 1 by any suitable means such as by a setscrew 48. In order to retain this bar in position a leaf spring 49 is shown as provided with a hooked up per end 50 engaging over the top of the ring 1-7 and an inwardly bent rib 51 which may engage beneath the edge of this ring, or in a notch 52, this leaf spring -fl9 being fixed to the lower portion of the member 45 by means of a-screw The lower end oiithe member 41:3 is cut away on opposite sides as at 56 and has a transverse slot 57 therein, this slot connnunicating with a central circular perforation 58 in which may be seated. a coil spring 59 bearing at its upper end against the base of the perforation 58 and at its. lower end against the central reduced port-ion'GO of a spool shaped tension member 61. This central portion 60 is adapted to ride in the slot 57 and the circular end portions 62 ride in the cut away portions 56. The spring 59 urges this spool shaped member downwardly as fa as permitted by a stirrup shaped strap 63 which extends up on opposite sides of the member 50 and fixed thereto by means of a screw 641-. The lower portion of this member (33 forms a support for the tape 10 which passes there over; and between it and the tension member 61. This ion member cl irly shown in Figure at and bears only against the marginal portions of the tape which are left uncut by the knife 14.

In order to facilitate the threading of the tape over the member 63 and beneath the spool shaped tension member means is provided for raising this member against the tension of the spring 59. As shown this comprises a finger lever 65 pivoted at 66 with the rear face of the member 50 and having depending therefrom at one side of its pivot an L shaped rod 67 the lower inturned member 68 of which passes beneath the central portion of the member 61. By raising the outer end of the finger lever 65 the rod 67 is raised and its lower end en gaging the tension roller causes this roller tobe raised also. This tension device is not claimed herein but forms the subject matter of a divisional application Serial No. 251,089, filed February 1, 1928, for tension devices.

After the setting of each stud, as the punch and setting mechanism reciprocates preparatory to forming a succeeding hole through the tape and the work, the tape is held to the work by the hooks previously set and passes through the tension device as this moves with the punch and setting mechanism toward the tape guiding and weakening mechanism at 5, this exerting a tension on the tape in the direction of work feed, causing the tape to automatically conform to the direction of the pull from each stud to a succeeding stud so that it is thus conformed to the contour line of the series of studs as set in the work even though this line be curved.

After the desired series of studs have been set the operator releases the work from the work table which is accomplished by raising the presser foot such as is commonly used in connection with machines of this kind. Simultaneously. with this raising of the presser foot the weakening of the tape is effected by slitting it with the knife 14. The presser foot 70 is carried at the upper end of a rod 71 and is normally held down yieldingly against the work by means of a spring 72. The lower end of the rod 71 rests on one end of a lever 73 (Fig. 19) the opposite end of which is connected by means such as a chain 730 to the forward end of a treadle 74. From the rear end of the treadle extends the usual clutch control rod for starting and stopping the machine. In order that motion of this wedge shaped member may be effective for the purpose, (regardless of the position of adjustment of the weakening mechanism alon the slideway 6, the wedge shaped meni ber 33 is extended for some distance along the slideway 6. At one portion of its length it is provided with a rearwardly extending shank portion 75 mounted to slide longitudinally over the upper face of the support 7. It maybe fixed thereto by means of a screw 76 passing through a slot 77 in this shank portion and engaging in the sup port 7. To one side face of this shank portion 75 is fixed one end of a hook shaped leaf spring 78 which has an outwardly turned curved end 79, the intermediate portion 80 thereof being substantially parallel to the inclined rear end 81 of the shank. .Adapted to bear against this inclined end is a cam roller 82 carried at the'end of an arm 83 pivoted on a screw ivot 84 fixed to the, rear end of the support 7 As the pivot screw 84 is substantiallyin line with the central axis of the shaft 77 motion of the roller 82 across its inclined rear face toward the side on which the spring 78 is fixed forces the shank 75 outwardly so as to move the wedge shaped portion 33 beneath the inner end of the lever 30, causing this lever to rock and bringing the knife down to slit the tape and the clamping plate down to clamp the tape. Subsequent movement of the roller 82 against the inner face of the spring 78 along the portion 80 as the arm 83 is moved to bring the roller from behind the shank 75 causes this shank to be reciprocated and thewedge shaped member 33 moved from beneath the lever 30, whereupon the spring 27 causes the knife and clamping plate to be raised to inoperative position.

In Figure 14 is shown a modified construction of knife actuating means in which in place of the lever 30 shown in Figures 2, 3 and 13, a bell crank lever 300 issubstituted. Thisbell crank lever has one arm engaging the crosshead carrying the knife and clamping plate and its other arm is upwardly extended and rounded as at 301 to engage with a slot 302 extending longitudinally in the lower face of a bar 303 which extends parallel to the guide member 6. Fixed to or integral with this bar is a shank portion 304 which is mounted to slide over the upper face of the support 7 in the same position as the shank portion 75 hereinbefore described and which is substituted. in place thereof when the modified form of lmife and clamping plate actuator is used; as the shank 304 is moved by the roller 82 the knife and clamping plate are positively actuable in both directions of motion. With this modified construction the springs 27 for raising the knife and clamping plate are unnecessary.

In order to actuate the; arm 83 in this manner, a link 85 is pivoted at 86 thereto, the opposite end of this link engaging in one arm of a bell crank lever 87, to the horizontal arm 89 of which is fixed a rod 90 extending to the forward portion of the treadle 74 for actuating the presser foot (Figure 19). Whenever this treadle there fore is depressed to raise the presser foot to release the work, the knife and clamping plate are brought down to weaken the tape and to clamp it between this weakened portion and the hook setting mechanism.

In machines of thisoharactcr mechanism is commonly provided for regulating the spacing of the fasteners as set in the goods, for this purpose the feedmovement of the punch and set mechanism being variable. If the spacing of the fasteners is varied it will be apparent that the length of the section of tape to be fixed in position by a series ofa given number of fasteners will also vary and provision is therefore made in this invention. by which adjustment of the feed of the punch and set mechanism also produces adjustment of the distance between the tape slitting device and the punching position of the punch and set. As the slitting of the tape to define the length of the tape section to be affixed by the series is accomplished before the series has been set, it is evident that the number of fasteners to be included in each series must be known prior to the slitting of the tape in order that the proper length of section may be defined. Commonly in the manufacture of shoes where lacing hooks are employed either three or four books are set in each series. Consequently provision is made for anadjustment of the position of the tape slitting mechanism in addition to that required for different spacings of fasteners in order to correspond with a series of four and a series of three lacing hooks.

These adjustments are effective by a mechanism more particularly illustrated in Figures 1, 6, 13,15, 16, 17 and 18. Referring first to Figures 17 and 18, at isshow-n a frame piece extending rearwardly from the machine on which is pivoted at 96 a gear segment member 97. This member, 97 is provided with an actuating handle 98 by which it may berocked and it is also provided with a pointer 99 which may co-operate with a suitable scale (not shown) carried by the frame in order to indicate the position of adjustment of the handle 98. This gear segment meshes with a segment 100 carried at one arm of a bell crank lever 101 fulcrumed at 102. The other arm 103 of this bell crank lever is connected to a link 104 which leads to the mechanism by which the amplitude of motion of the setting mechanism carrier 1 is controlled andmay correspond to the link connecting the members 0 and 0 shown in Figure 7 of the Glass Patent No. 811,839 granted February 6, 1906 for machines for setting lacing hooks or studs. By rocking the handle 98, therefore, the amplitude of motion of the punch and set carrier 1 is regulated. At the pivotal connection between the bell crank arm 103 and the link 104 there is positioned a screw 105 which is locked against the outer face of one of'these members by means of a lock nut 106 (see Figures 1,13 and 15). This screw 105 is centrally perforated and threaded for the, receptionof a. screw 108 having a ball head whichis engagedwith a correspondingly shaped socket 110 in one end of: a link 111'. The socket 110 may be formed by. means of a hole extending through. the link 111, the material of the link about the margin of the hole on the inner sidebeing turned over as shown at 112 sufficiently to retain the ball in position. This construction provides a universal joint connection between the link 111 and the screw 108. The opposite end. of this link 111 is slotted as at 116. Through this slot passes a screw 113 threaded into a block 114, a washer 115 being positioned beneath the head of the screw 113 by which construction the block 1141nay be adjusted lengthwise of the link. This adjustment provides for changing the numbers of fasteners to be set in each series.

Within the block 114 is a socket in which extends a ball head121 of a post 122 which isfixed to-an arm 123. The head 121 may be held within the socket by any suitable means, but as shown a screw 124 havin a cup shaped inner endis threaded into the block and bears against this head, a lock nut 125 being employed to retain the screw 124 in fixed position. The arm 123 extends through a slot 126 in the upper end of a vertical shaft 124 which is journaled in a frame piece 127. A screw 128 may. be employed to fix the arm- 123 in position in the slot 126. Beneath the frame member 127 the shaft 124 carries a gear segment 129 which meshes with a similar segment 130 journaled on a vertically extending post 131. This segment piece 130 has an arm 132 extending therefrom ancb to the outer end of this arm is pivoted ona stud 133 projecting downwardly therefrom one endof a link 134. This link asshown is held inposition on the stud 133 bymeans of a1 washer 135 beneath which acotter pin 136 'is passed through the stud. The opposite endof this link 134 is pivoted to a post 137 extending upwardly from the rear portion ofthe block 8. This; end of the link is held in position on this post by any suitablemeans such as a washer138 above which a cotter pin 139 is-passed through the post 137. By this means it is seen that whenever the handle 98 controlling the length of stroke of the punch and set mechanism andconsequently the spacing of'the fasteners set in the material, the block 8 is also=moved along the slideway 6 in a correspondingymanner and that by adjusting the effective length of the link 111 by means of its screw and slot connection to the block 114 a further adjustment of the position of the block 8 is effected independent of the spacing adjustment to provide for either three or four fasteners to be set in each series.

Figure 11 shows fourlacing hooks set in series in a length of the goods through a section of tape defined by cuts through the tape at a and b where the tape is severed. Figure 12 shows three lacing hooks set in a similar section. It is found where three hooks are desired to be set in series that in order to avoid a short tape end extending beyond the last hook of the series and a much longer end extending beyond the first hook it is necessary to draw back the length of tape somewhat from its position when four hooks are to be set. For this purpose the tension mechanism hereinbefore described is positioned as shown in Figure 10 with the rib 51 of the supporting spring 49 engaging in the notch 52 so that the tape is lifted somewhat as shown in Figure 10 and its forward end drawn backwardly so that the punch and set mechanism as it descends passes nearer the free edge of the tape. In dotted lines in Figure 12 is shown the position in which the fasteners would be set in the tape if the tension mechanism were in its lowered position as shown in Figure 6, while in full lines is shown the correct position of the tape for a series of three fasteners, the tension mechanism being set as shown in Figure 10.

It may sometimes happen that one or more fasteners of the series fail to be set in the normal running of the machine. v hen the tension mechanism is in its raised position,

as shown in Figure 10, its lower end is suf-' ficiently raised above the work so that it will clear the tops of fasteners set in the work. When it is in raised position therefore, single fasteners may be set in the work in case it shall be desired to effect repairs as when one or more fasteners should have been skipped in the normal running of the machine, or when, for any reason, it should be desired to set individual fasteners out of their usual sequence with others of a series and in any portion thereof. Ordinarily, of course, it would not be desired to present the tape to the setting mechanism while re pairs of this kind are being made. I

In order to properly direct the'work over the work table 4, an edge gage projecting therefrom may be employed, such a gage being shown at 150 in Figures 7, 8, 9 and 13. This gage comprises a substantially rectangular block having a rounded end and whose inner end extends over the work table. It is found in practice that different operators require different settings of this edge gage even for the same classes of material and it is in an inconvenient position for adjustment. A novel adjusting mechanism therefore has been provided which is readily accessible to the operator. Figures 7, 8 and 9 the edge gage has depend ing therefrom a pin 151 which is mounted to slide iii a slot 152 in an ear 153 extendin rearwardly of the work table 4, the

As shown best in table having fixed thereto an upwardly and rearwardly extending arm 15 This gage is therefore capable ,of longitudinal adjustment in the slot 152 and also rocking adjustment. The pin 151 is slotted on opposite sides as shown at 155 and taking through these slots is a wedge member 156 having a central slot 157 to receive the uncut central portion of the pin 151. The slots 155 form an inclined head 158 at the lower end of the pin which engages with one face of the wedge member 156. It is clear therefore that by pushing outwardly on the wedge member 156 the gage may be brought down firmly against the work table and by retracting this wedge member the gage member may be release. In order to move this wedge member it is shown as provided with a laterally extending slot 160 in which rides a head 161 on a screw member 162 threaded through the arm 154 and accessible on the opposite side'from the wedge member, (as shown best in Figures 8 and 9), by a screwdriver. By turning this screw 162 in one direction, as shown in Figure 9, the wedge. is retracted, releasing the gage, and by turning the screw in the opposite direction as shown in Figure 8, it is clamped in position. As shown the pin member 151 is provided with a head 170 with rounded ends which fits in a counterbored portion 171 in the upper face of the gage member.

Having thus described certain embodiments of this invention it should be evident to those skilled in the art that various changes and modifications may be made therein without departing from its spirit or scope as defined by the appended claims.

The combination with a fastener setting machine having fastener setting mechanism, of means for presenting a reinforcing tape to be fixed to the work by fasteners set by said mechanism, means for cutting the tape at intervals between its side edges, and means engaging the tape along its uncut margins for applying tension to said tape.

17. The combination with a fastener setting machine having fastener setting mecha nism, of means for presenting a reinforcing tape to be fixed to the work by fasteners set by said mechanism, means for cutting the tape at intervals between its side edges, means engaging the tape along its uncut margins for applying tension to said tape, and means actuable to release such engagement to facilitate threading of the tape through said tension applying means.

18. The combination with a barrel fastener setting machine having fastener setting mechanism, of means for presenting a tape to said mechanism to be fixed to work by fasteners set by said mechanism, means for partially severing said tape, and means engaging an uncut portion thereof between said severing means and setting mechanism for applying tension to said tape.

19. The combination with a fastener setting machine having a fastener setting mechanism, of means for presenting a tape to said mechanism to be fixed to work by the fasteners set by said mechanism, means for slitting the tape between its edges, a spool shaped member having end flanges spaced to bear on the uncut margins of the tape, and a spring pressing said member against the tape to apply tension thereto between said member and said mechanism.

20. The combination with a barrel fastener setting machine having fastener setting mechanism, of means for presenting tape under tension to said mechanism to be fixed to the work by a series of fasteners, said presenting mechanism including parts positioned adjacent to the surface of the work when in said operating position, and means for supporting said parts further removed from the work to clear fastenings which may have been previously set.

21. The combination with a barrel fastener setting machine having fastener setting mechanism, of means including a tension device for feeding tape to said mechanism to be fixed to work by a series of fasteners set therein, and means for selectively supporting said device from said mechanism in either of a pair of elevated positions in the upper of which position it will. clear the tops of fasteners which may have been previously set in the work.

In testimony whereof I have afiixed my signature.
